I drew the hr8201 industrial keyboard main control chip on Taobao onto the 2230 size board with the mini-PCI interface. The interface definition refers to the standard m.2 definition. Of course, I don’t want anyone to actually put this thing on the m. .2 interface is plugged into this keyboard master control solution that costs less than six yuan. If you want to add lights, you can add additional light controls.
The precautions and array definition are all here. In addition, the VSS in the description is +5V in my schematic.
In addition, the GND of the socket is not lead out. If necessary, please fly the wire from the tail pad yourself.
